二○一六 年 四 月 三十 日 译文题目： 基于SSH的web技术介绍 原文题目： SSH based web technology introductio 原文出处： http://wenku.baidu.com/view/7c5f2560f5335a8102d22073.html 1 SSH based on Web Technology 1、Introduction One preface along with the Java technique of gradual mature and perfect, Be establishment business enterprise class application of standard terrace, the J2 EE terrace got substantial of development .Several technique asked for help from to include in the J2 EE norm : Enterprise JavaBean (EJB), Java Servlets (Servlet), Java Server Pages(JSP), Java Message Service(JMS)...etc., development many application system.But, also appeared some problem in the tradition J2 the EE the application of the development the process: 1)the antinomy of of data model and logic model. Currently the database of usage basically and all is relation type database, but the Java be essentially a kind of the language which face to object, object at saving with read usage SQL and JDBC carry on a database operation and lowered plait distance of efficiency and system of can maintenance; 2)tradition of J2 EE application much the adoption is according to the EJB heavy weight frame, this kind of frame suitable for develop a large business enterprise application, but usage the EJB container carry on development and adjust to try to need to be waste a great deal of time.For lowering the Ou of code to match sex, exaltation system of development efficiency, this text put forward 1 kind EE according to the J2 of the Struts frame and Spring frame and the Hibernate frame application development strategy.

2、Use the Struts realization MVC structure use the Struts realization MVC structure MVC(Model-View-Controller) is put forward by the Trygve Reenskaug, first drive application in the environment SmallTalk-80, is many to hand over with each other with interface system of 2

constitute foundation. According to the need of variable of the interface design, MVC hand over with each other constitute of system to resolve into model and see diagram, controller three part. Model(Model) is software processing problem logic at independence in outside manifestation under contents and form circumstance of inside abstract, packed the core data, logic of problem and function of calculation relation, independence in concrete of interface expression and I/O operation. See diagram(View) mean information and particular form demonstration of model data and logic relation and appearance to the customer. It acquire a manifestation information from the model, there can be many for homology of information dissimilarity of manifestation form or see diagram. The controller(Controller) is a processing the customer hand over with software with each other operation of, its job is control provide model in any variety of dissemination, insure a customer interface among the model of rightness should contact; It accept a customer of importation, give° the importation feedback model, then realization compute model control, is make model and see diagram to moderate work of parts. Usually 1 see a diagram rightness should a controller. Model, see separate of diagram and controller, make a model be able to have many manifestation to see diagram. If the customer pass a certain see the controller of diagram change the data of model, all other dependence in these see of data diagram all should reflection arrive these variety. When therefore and regardless occurrence what data variety, controller all would variety notice ally see diagram, cause manifestation of renewal. This is actually a kind of variety of model-dissemination mechanism. The Struts frame is to be the item of Apache Jakarta to constitute part to publish luck to do at the earliest stage, it inherited MVC of each item characteristic, and did according to the characteristics of J2 EE correspond of variety with expand. The Struts frame was good to combine Jsp , Java Servlet , Java Bean, Talia etc. technique. In the Struts, what to undertake the controller role in the MVC be an ActionServlet. The ActionServlet is an in general use control module. This control module provided a processing all HTTP claim which send out Struts of entrance point. Its interception with distribute these claim to arrive correspond of action type.(these action all of type
